Wish I could, but our local track is actually a large go-kart track and there's no SM lap times to compare. I am within a few seconds of the lap record for Miata's if that's means anything. (with less suspension mods)

Does it seem that the FM provided studs and nuts don't have the problem and BEGI's do?

I don't believe the "longer on the loud pedal, faster driver" theory. A setup with 2* less timing and slower driver would have higher EGTs, and a slower driver on a track with a longer straight would stand on the gas longer than Sav.

I made my speed comment because I've seen a direct correlation between the speed of the turbo car and the occurrence of this issue. The guys who do 1-2 track days a year, full-weight street cars on street tires, never have a problem. The guys who are on r-comps, doing 6+ events a year, and actually going fast, have the problem. I recall VagaXT commenting on how he never had the problem, and then he showed up to Streets in December with NT-01s, laid down some stupid fast laps - and struggled all day long with nuts and studs backing out.

or maybe you're just driving like a *****. Seriously. Do you go out there for blood or to cruise around and "have fun"? I go to the track because my mother never loved me and I never met my father, and now you have to ******* respect me or I'll wear your face as a ******* mask.

You said you were within 3 seconds of the GJMS record, which was (I presume) set by one of the FM cars. I don't want to sound like a dick here, but I know how fast I am in comparison to the cars that are 3 seconds ahead of you. I came very close to rear-ending the **** out of the Westfield exiting turn 6 at Laguna in March. I don't think there was an FM car within 5 seconds of me.
3 seconds on a 1-minute track puts you around 10-12 seconds slower than the cars we are talking about here. Certainly a respectable time, but not really on the same page as the cars we are discussing here.

Since I haven't tracked this year yet I'll use my last years experience.
My manifold is a custom 45deg/topmount SS log, 3" SS downpipe, no gaskets, no leaks(machined flanges) with a 2871 and I was using shitty bolts everywhere.
I was shearing studs like I was cutting disco in 79', winning or in the top 3 at every track event up here (I know that's not saying much really), so I beat the **** out of the car quite often but I'm sure my problem was my exhaust system and the amount of pressure/weight that was acting on the turbo system.
The exhaust is a full 3" system with magnaflow muffler (mild steel), has a flex pipe right after the dp and weight to much imo.
I eventually broke the weld and the turbo inlet flange right in half after I sheared two bolts and keep going, vibrations ftl.
This year I'm running a v-band at the dp-exhaust system, arp bolts, and I'm rehanging the exhaust and using different hangers (rubber garabage sucked and move to much) and that should fix my issue, I hope.

Haven't run this year yet with the new turbo setup, MS, coilovers and 225 hankooks. I'm going to guess I could pick up at least a second. We'll see...

Still waiting on details of new build.
